Here’s a list of the major projects I’ve worked on and my key publications. You might also be interested in my presentations, my full CV, or my ORCID profile. My peer review history is also available on Publons.

Since April 2020, I’ve been part of the Delphi group’s COVID-19 response team. Delphi produces the COVIDcast web site and API, containing real-time data on the pandemic across the United States, and obtains data from unique sources. After time as co-manager of the engineering team, I moved to the the COVID-19 Trends and Impact Survey (CTIS), conducted in collaboration with the University of Maryland and Facebook. I am now Principal Investigator (with Robin Mejia) of the United States version of the survey.

My work with Delphi resulted in the following papers, along with several posts on the Delphi blog:

Delphi and its collaborators have received several awards for this work, including:

- The 2021 American Statistical Association Statistical Partnerships Among Academe, Industry, and Government (SPAIG) Award
- The 2022 AAPOR Policy Impact Award, for CTIS
- The 2022 AAPOR Warren J. Mitofsky Innovators Award, also for CTIS

During my PhD thesis I worked with Joel Greenhouse to design statistical models to predict crime by using crime hotspots, spatial features, seasonal factors, and leading indicators (like 311 calls, criminal mischief, and so on). My goal is both to improve crime prediction and to provide inference tools for criminologists to understand factors that lead to crime. I also work on evaluation and diagnostic methods to understand the performance of predictive policing models.

My dissertation work was supported by a National Institute of Justice Graduate Research Fellowship (GRF-STEM).

More recently, I have pursued other applications of point process models, such as to the modeling of wildfires and their associated risks.

I have an active interest in statistical pedagogy, and in developing new ways to improve student learning, assess understanding of statistical concepts, and better teach the foundations of statistical reasoning. I help lead the Teaching Statistics Group at Carnegie Mellon University’s Department of Statistics & Data Science.

As an undergraduate I started a project (supervised by Alex Athey of Applied Research Laboratories) to devise methods to continuously monitor the radiation background in a wide area and detect any sudden changes, such as might be introduced by a dirty bomb or stolen radioactive source. We built a system which uses gamma spectroscopy to compare new measurements to previous observations of the radiation background, making it feasible to monitor a wide area with mobile detectors and rapidly detect changes.

At Carnegie Mellon University, I continued the project under Valérie Ventura and Chad Schafer, proposing a new method based on Kolmogorov–Smirnov tests. James Scott and Wesley Tansey continued the work to devise a new spatial smoother for radiation spectra.

My book *Statistics Done Wrong* was published in March 2015 by No Starch Press. Covering common statistical errors present in a wide range of current scientific research—not just simple misuses of *t* tests but failures of statistical power, unnoticed pseudoreplication, effect size inflation, and much more—it has since been translated into German, both simplified and traditional Chinese, Japanese, and Korean.
